Hi, muzammil.

All these three colleges, you asked about are the best three engineering colleges in and around pune and Mumbai. 

PCCOE has the best reputation of having better placements, best teachers, nice hostels and packages of companies for the students. Most of the people prefer this college.

DY patil college also have the same facilities but these college do have less placement packages for the students compared to the PCCOE college. 

DJ Sanghavi college is also good but have problems with the administration works and limited number of classrooms and it also has high fees but its facilities are very good compared to the other two.

Ranking of the colleges will be better if you read my answer and then you align these according to which you prefer better

Goodluck
